DAMPERS

AERO

• Front Wing: 4 (of 6)
• Rear Wing: 5 (of 6)
• Downforce level: High-biased rear (planted through Eau Rouge/Raidillon and Blanchimont)
• Brake Ducts: Front 4 / Rear 3

KEY SETUP NOTE

• Run slightly more rear wing than instinct suggests — the 720S snaps loose on power and under compression, and Eau Rouge/Raidillon plus Blanchimont will punish any rear instability at full commitment; sacrifice a little Kemmel top speed for a car that stays planted through the flat-throttle sections where lap time is actually won on a single hot lap.

TRACK GUIDE

• La Source: brake late but in a straight line — trail brake gently only to rotation point; this car's mechanical grip lets you carry more entry speed than expected, but early turn-in with front load will understeer wide.
• Eau Rouge/Raidillon: full commitment flat or near-flat depending on fuel/tune; keep the car dead straight over the compression — any steering input here with a nervous rear will snap the McLaren loose at the worst possible moment.
• Les Combes: heaviest braking zone on track after Kemmel — brake in a straight line, use the stability from brake bias/engine braking settings, then rotate hard on entry since the coast diff lock helps settle the rear.
• Pouhon: needs commitment on entry with stable front — trust the aero platform, carry speed through both apexes, small correction only.
• Blanchimont: this is where quali laps are made or lost — flat-out or as close as possible; the car must be planted, so any rear-end aero deficit will cost massive time or a spin.
• Bus Stop: aggressive kerb use is fine — the 720S handles kerb strikes well with these damper settings; sacrifice a clean line slightly to carry more speed onto the pit straight.

THEORETICAL BEST LAP

• 2:18.900 — theoretical optimal sector composite, dry, low fuel, qualifying
